5. A receipt production method comprising: executing, by a payment processing terminal, a payment process and generating payment information; adding, by the payment processing terminal, identification information to the payment information and sending the payment information and the identification information through a network to a server for storage; sending, by the payment processing terminal, location information of the server and the identification information associated with the payment information by wireless communication to a mobile terminal; acquiring, by a printer, the location information of the server and the identification information associated with the payment information from the mobile terminal when the mobile terminal to which the location information of the server and the identification information were sent communicates by wireless communication with the printer; sending, by the printer, a request for transmission of the payment information to the server using the identification information and the location information of the server acquired from the mobile terminal; acquiring, by the printer, the payment information associated with the identification information from the server in response to sending the request; and printing, by the printer, a receipt based on the acquired payment information.

6. The receipt production method of claim 5 , further comprising: sending, by the printer, information to the server indicating that the receipt was printed when the receipt is printed based on the payment information; and avoiding, by the server, transmission of the requested payment information in response to receiving the information indicating that the receipt was printed.

7.
